UNIDEN Model uh089sx UHF CB Radio
Introduction
The Uniden uh089sx is designed to provide you with years of trouble free service. Its rugged
components and materials are capable of withstanding harsh environments. Please read this
Operating Manual carefully to ensure you gain the optimum performance of the unit
The following system checks should be made every six to twelve months:
Check the Standing Wave Ratio (SWR).
Inspect the tightness of all electrical connections.
Inspect the antenna coaxial cable for wear or breaks on the shielding.
Inspect the tightness of all screws and other mounting hardware.
Should the unit malfunction or perform poorly, follow these procedures:
Check the power cord and fuse.
Check the VOLUME control setting. Be sure the SQUELCH is
adjusted properly. Possibly the radio is over-squelched.
Check that the transmission line (coaxial cable) is
connector. Check that the antenna is fully extended for proper
operation. Check that all transmission line (coaxial cable) connections are secure and free of
corrosion.
The citizen band radio service is licenced in Australia by ACMA Radio-communications
(Citizen Band Radio Stations) Class Licence and in New Zealand by MED General
User Licence for Citizen Band Radio and operation is subject to conditions contained in
those licenses.
Blackening may occur on the Liquid Crystal Display if the uh089sx has been
subjected to extreme high temperature (above 60°C) . This is not a fault. Normal LCD
operation resumes when the temperature stabilizes back to standard operating
operating condition (0-55°C).

Operation
Setting the Squelch
Turn the Unit ON by
rotating the volume control
clockwise. Turn the outer
ring of the control to adjust
the Squelch.
You must select a
channel which is not in use before setting the
SQUELCH control. (see below for "Selecting a Channel").
Think of the squelch
control as a gate. If you
turn Squelch fully
clockwise it raises the
'Squelch gate' so high that
no signals get through.
If you turn the Squelch
fully counterclockwise it
lowers the 'Squelch Gate'
to the extent that all
signals get through -
weak, medium and strong
signals and noise.
To set the 'Squelch Gate'
to the desired level, turn
the squelch knob
counterclockwise until you
hear noise. Then carefully
turn the Squelch knob
clockwise until the noise
fades. Now only strong
signals get through.
Monitor
Press to open the squelch and receive all weak
signals.
Press again momentarily to cancel.

Turn the Rotary Channel Selector to

reserved for Emergency Calls.

UNIDEN Model uh089sx UHF CB Radio
Operation
Transmitting
Call Function
The uh089sx uses the 40 UHF-CB Channels
Select the desired channel. Press the microphone's PTT
button and speak normally into the microphone. Hold it
approx. 7cm from your mouth. Release the PTT button to
end the transmission and listen for a reply.
Press the microphone Call Button. A two second ringing tone will be transmitted.
You may select from 2 types of tones (see p.10).
(Channels
22 and 23 are for telemetry and telecommand
applications. Transmit is inhibited on these channels).
Current regulations require calling tones to be restricted to one transmission per
minute. If a second transmission is attempted within one minute then an error
tone will sound.
Using Repeater Channels
UHF CB repeaters are used to retransmit or relay your signal. Repeaters will extend
the range of your radio and overcome the shielding effect caused by solid
obstructions. In normal Simplex operation, your radio transmits on one particular
frequency and receives on that same frequency. If there is a barrier that partially
blocks your transmitted signal, the probability of another radio receiving the signal is
very slim. Hills, tall buildings, metallic structures,...etc tend to act as a screen between
radios.
Standard Operation without the aid of a
Repeater Station.
Operation with the aid of a Repeater
Station (Duplex).
The signal coming from your radio is received by the Repeater Station and the
re-transmitted at the same time on another channel. This operation is called
"Duplexing".
For example,
CH01 on Duplex Mode will Receive on CH01 but Transmit on CH31
CH02 on Duplex Mode will Receive on CH02 but Transmit on CH32 etc...
If you transmit on CH01 Duplex mode, you are actually transmitting on CH31 the
repeater station down-coverts your signal and retransmits on CH01.

Operating the uh089sx in Duplex Mode
For this example we are adopting CH01 as the channel being used in your area for
repeater use.
Press to switch Duplex On.
If Duplex is not required - press
again to switch Duplex off.
Only channels 01 - 08 are
available for Duplex.
The uh089sx has a scanning feature that allows you to search for active channels
automatically.
Furthermore, the uh089sx is designed
to have two types of scanning; Open
Scanning (OS) and Group Scanning
(GS), to give you flexibility and allow
you to use the radio more effectively.
Press and Scanning starts.
The icon appears.
The scan direction can be changed
at any time by rotating the channel
selector left or right.
Allows continuous scanning of all selected channels.
If an active channel is found, scanning will stop on that channel.
If the received signal ceases, the unit will wait 3
seconds for the signal to return, otherwise
scanning resumes.
To skip the active channel, press momentarily. Scanning resumes. To deactivate
SCAN, press or the PTT button on the microphone.
Check with your local Retailer for
information on available repeaters.
If SCAN is deactivated while on an active channel, the uh089sx will stay on
that active channel. If no channels are active, the uh089sx will reinstate the
starting channel.

Group Scan (GS) Mode
Allows you to monitor a Priority (Instant) Channel
while scanning (Instant Priority channel see p. 11)
To use GS Mode Scanning, press . GS icon appears on the display.
GS Scanning checks the Instant Priority Channel for activity regularly.
To deactivate SCAN, press the button or the PTT button on the
microphone.
If the Priority Channel becomes
active the radio will stay on that
channel for as long as the signal is
present. If the received signal
ceases, Priority Scanning continues
after 3 seconds.
If scanning stops on a channel
which is not a Priority Channel,
uh089sx will continue monitoring
the Priority Channel for activity
while listening to the active one.
Select which Scanning Mode you
wish to use - OS or GS.
Select the channel you want to
store.
Press to store. MEM icon
appears and a short tone beep is
heard.
To remove the channel from
Memory, press once more.
The MEM icon disappears.
If SCAN is deactivated while it is tuned to an active channel, the uh089sx will
stay on that active channel.
If none of the channels are active, the uh089sx will reinstate the scan start
channel.
If OS/GS Scanning is initiated when there are no channels programmed in
OS/GS memory, an error tone will be heard and scanning will not start (see
Programming Scan Channels - below).
